I am also wondering how she knows this. I'm like you and assume it's from talk around town. I'm less worried about SS's background than I am the men she was with. Are they known drug users? Do they have rap sheets? Are they good kids that possibly partied too hard and something went wrong?
When I say SS possibly could have OD'd, previous drug use doesn't play into this for me. Lots of things do. OD could be alcohol poisoning, it could be they slipped her something and she OD'd, it could be that it was the first time she ever tried drugs and OD'd.
My gut feeling is whatever happened was an accident and wasn't planned by the men. Covered up by the men, yes, but maybe not planned. Since her phone didn't go off until 8:30, I'm leaning towards they all fell asleep (or, possibly one or two of the men went home), he/they woke up and she had died during the few hours they were asleep. Man/Men panicked and disposed of her versus calling 911 because they knew she was dead. Alcohol poisoning is real as we all know and it's just possible she expired because of this. It's also very possible they wanted more from her sex wise than she was willing to give and things went horribly wrong. The background of these men would factor into several of my thoughts on what happened.
It would shock me if all three men (or even one) left their phones at home while taking her body somewhere. How can LE not yet know the pings of those phones, or, have a map of where they were? I'm SURE they do, just thinking outloud of how I'm surprised her body hasn't been located.
I still believe there is a SLIM chance she did leave on foot. As a teenager I was at a party and I had no idea where I was. Some bad things went down and I was scared to death and just left. I can see it happening if she was truly scared. Doesn't matter how cold or what shoes she was wearing, when you are scared for your safety, you get out of there. I don't think this is what happened, but I'm not 100% ruling it out. But....how far did she get that they can't find her? I don't think it would have been far. Could she have called for a ride? Yes, does LE know who that was? Possibly, and possibly they are keeping it quiet while looking into that angle and why they are searching farther away (but I doubt it).
I still also find it confusing on the number of people she was, or wasn't, with. Are there more players? I'm like some of you, did they go anywhere in between? Did they stop at one house and end up at another?
2:30AM leaves bar to go 40 minutes away. An hour tops to get to the "searched" house? 3:30AM. Phone goes off at 8:30AM. What happened in those 5 hours? Did they make several stops? Did they go straight to the house that was searched, party another hour two, crash then wake up to her dead? Did something happen on the WAY to the house and she died? Did they dispose of her within those 5 hours only to find her phone in their car or at their house at 8:30 and turn it off then destroy it? Way easier to get rid of a phone than a body at a later time.
So many questions. I don't think she is alive at this point and that's heartbreaking to me for her family and children. She was 22. Yes, a lot of bad mistakes, probably not a lot of direction from the adults in her life. Did she deserve to die? Absolutely NOT!
These are just my rambling thoughts......
